Hi,
The GPMC is a unified memory controller dedicated for interfacing with external memory devices like - Asynchronous SRAM-like memories and ASICs - Asynchronous, synchronous, and page mode burst NOR flash - NAND flash - Pseudo-SRAM devices
This driver will take care of setting up the GPMC based on the settings specified in the Device tree and then probe its children.
cheers, -roger
